It is because they want to up the difficulty as most people have the EXP Share, an item that made the storyline in the main games too easy. The EXP Share allows your Pokemon to be similarly leveled without much grinding.

A good way to level up your Pokemon is by grinding Adventurer Jesper in the 2nd level of Cragonos Mines, as he awards over 5000 XP for your Pokemon, while also giving you a small amount of money as well.
